Descriptions

This honors undergraduate thesis examines the process of simulating power system state estimation, the use of the alternating direction method of multipliers in the problem of distributed power system state estimation, and provides a rudimentary asynchronous implementation of the above for a linearized DC power system. The asynchronous implementation is applied to a model of the IEEE 57 bus test system; convergence to a set of centralized state estimates and to the true state of the system is examined and compared to the results of a control synchronous implementation of the ADMM algorithm whose iterations were restricted by the weighting factors of the asynchronous method. We find that the state estimation from the asynchronous ADMM algorithm satisfactorily converges to estimates done by a centralized state estimator as well as the real states of the system; we conclude with future work that can follow from these conclusions.
